Biometric Authentication Server Using Area-Based ID Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the scale of biometric authentication services grows, the increasing number of biometric information in databases leads to a decrease in authentication accuracy, potentially causing false authentications and resource inefficiencies.
Innovation Solution
A system where authentication terminals maintain an ID list of individuals in a predetermined area and transmit biometric information and IDs to a server apparatus, which performs biometric authentication using reduced and targeted biometric information for improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of biometric information in the database increases to accommodate more users, then the service scale expands, but the authentication accuracy decreases
Solution Approach 1:
The patent segments the authentication process into two stages: first, the authentication terminal performs local matching against a small set of biometric information of persons in the predetermined area to identify candidate matches; second, the server performs detailed authentication only for these candidates. This segmentation reduces the effective search space from the entire database to a small subset, maintaining high accuracy even as the overall database grows.
Solution Approach 2:
The system performs preliminary action by pre-storing biometric information of persons in the predetermined area at the authentication terminal before actual authentication occurs. This preliminary preparation enables rapid local filtering, so when authentication is needed, the system only needs to compare against a small pre-defined set rather than searching the entire database, thus maintaining accuracy while supporting large-scale services.
2Reliability
If all biometric information from the database is transmitted to the authentication terminal, then complete authentication can be performed locally, but resource consumption and processing time increase
Solution Approach 1:
The patent extracts only the necessary subset of biometric information from the database - specifically, the biometric information of persons in the predetermined area - and stores it locally at the authentication terminal. This extraction eliminates the need to transmit or search through the entire database during authentication, significantly reducing processing time while maintaining reliability for the target user group.
3Adaptability or versatility
If biometric information of all users is stored and processed, then comprehensive authentication is achieved, but false authentications increase
Solution Approach 1:
The patent applies local quality by tailoring the authentication approach to the specific context of the predetermined area. Instead of using a uniform one-to-many comparison across the entire database, the system creates a localized one-to-one or one-to-few comparison environment by pre-storing biometric information of persons in that specific area. This localized approach reduces false authentications by limiting comparisons to relevant candidates only.
Data Source
AI summary
A system includes a server apparatus and at least one or more authentication terminals. The server apparatus stores an ID of each of a plurality of users and biometric information in association with each other. The at least one or more authentication terminals maintain an ID list that stores IDs of at least one or more persons staying in a predetermined area. The at least one or more authentication terminals transmit an authentication request, the authentication request including biometric information of a person to be authenticated and the ID list, to the server apparatus when an authentication of the person to be authenticated is required. The server apparatus extracts IDs included in the ID list from the ID of each of the plurality of users and performs biometric authentication using biometric information corresponding to the extracted IDs and the biometric information included in the authentication request.
